I have used Zoom pedals for years, the early ones were not so good but now they are really up to scratch. I use my B2.1u as a tone changer instead of using the tone filter on my MK Sig, the filters are fully open with Q's on, amp is adjusted for the room. Zoom have brought out a new unit - the B3 and it is similar to the Line 6 stuff so I think I will be getting one after the holidays, they are very new and I haven't seen any reviews on useage except people reviewing the look and info on it. Anyone on here got one yet?(i doubt it as I cannot seem to get a price on one here in the UK)
